Note: Some UDP definitions are in the Protocol or IP modules

`UDP_PROTOCOL_NAME = 'UDP';`

`MIN_UDP_PACKET = 8;`	Not Counting Adapter and Transport Header
`MAX_UDP_PACKET = 8192;`	Not Counting Adapter and Transport Header

`UDP_TIMEOUT = 0;`	Wait forever on a UDP Read
`UDP_BUFFER_SIZE = 65536;`	UDP Receive Buffer Size

`UDP_MAX_PORT = 65536;`

`UDP_HEADER_SIZE = 8;`	SizeOf(TUDPHeader);

`UDP_DATAGRAM_SIZE = 8;`	SizeOf(TUDPDatagram)

`UDP_PORT_START = 49152;`	First dynamic port (Previously 1024) As per IANA assignment
`UDP_PORT_STOP = 65534;`	Last dynamic port (Previously 5000) Short of IANA assignment to allow for rollover

Note: Some UDP definitions are in the Protocol or IP modules
Note: 8 Bytes
`SourcePort:Word;`	Network Order
`DestPort:Word;`	Network Order
`Length:Word;`	Network Order
`Checksum:Word;`

Note: 8 Bytes (Used by UDPBuffer)
`Size:Word;`	Word to keep size even
`RemotePort:Word;`
`Next:PUDPDatagram;`	Followed by RemoteAddress (4 or 16 Bytes)

Buffer	The complete packet including Transport header
Note	If checksum is zero then no checksum was added, return True.
